The Lab

The primary goal of our research is to understand in detail the structure-function relationship of proteins as dynamic systems. We are mainly focused on signaling linked to catalytic turnover,  the storage function of coiled-coil domains and mechanisms of complex formations and signal transduction within the  extracellular matrix. To reveal the structural and functional basics of the underlying molecular aspects of signaling, we use a combination of:

  • X-ray crystallography in combination with SAXS and Electron Microscopy
  • Several biophysical techniques  (a.o. DLS, AUC, DSC-ITC and CD-spectroscopy)
  • In vitro and in vivo functional analysis 
Our long term goal is to develop a molecular understanding of target proteins at work. The research will provide new insights into basic mechanisms of how these proteins function, and applied science of great biotechnological and biomedical importance will be advanced.
